Albedo Net.Time τ – PTP Grandmaster / PRC Time Server (ITU-T G.811)

Name: Albedo Net.Time τ – PTP Grandmaster / PRC Time Server (ITU-T G.811)
Brand: Albedo Telecom
SKU: 17779

Albedo Net.Time τ (Tau) is a carrier-grade PTP grandmaster and Primary Reference Clock (PRC) compliant with ITU-T G.811, with a built-in GNSS receiver and rubidium oscillator – a precise time and frequency source for 5G, backbone and telecom networks, data centers and financial institutions.

Albedo Net.Time τ (Tau) is a carrier-grade Primary Reference Clock compliant with ITU-T G.811. It is a PTP/NTP grandmaster with a built-in GNSS receiver and rubidium oscillator, designed as a source of precise time and frequency for 5G, backbone networks, data centers and financial institutions. Thanks to its universal protocol translator function, Net.Time τ accepts and delivers practically any time signal (PTP, NTP, SyncE, GNSS, ToD, 1PPS, T1/E1, MHz), allowing legacy infrastructure to be seamlessly integrated with the new PTP standard.

Net.Time as a universal time protocol translator: any input signal (GNSS, IRIG-B, NTP, PPS, SyncE, E1/T1) translated to any output.

Key advantages of Net.Time τ

PRC compliant with ITU-T G.811 – carrier-grade time and frequency reference for the entire network
PTP grandmaster (Telecom profile) + SyncE – meets the stringent phase and frequency requirements of 5G networks
Built-in 72-channel, multi-band GNSS (GPS, GLONASS, BeiDou, Galileo) – accuracy <40 ns, resistance to interference and spoofing
Rubidium oscillator + holdover – time maintained on GNSS loss (100 ns @ 10 h)
Redundant power supply and 19″/1U design, passive (fanless) operation
Universal protocol translator – PTP↔NTP↔SyncE↔IRIG-B in any input/output combination
Up to 512 unicast PTP clients, Web/CLI/SNMP management, RADIUS/TACACS+
Up to 10 years warranty – exceptionally low total cost of ownership (TCO)

Frequently asked questions (FAQ)

What is the difference between a PTP grandmaster and an NTP server?

A PTP grandmaster (IEEE 1588) delivers nanosecond-/microsecond-level and phase synchronization, required for example in 5G and power grids, whereas a classic NTP server provides millisecond-level accuracy. Net.Time τ combines both worlds – it is simultaneously a PTP grandmaster and an NTP server.

What is a Primary Reference Clock (PRC) according to ITU-T G.811?

A PRC is the top-level reference clock with the highest class of frequency stability in a telecom network. Net.Time τ meets the G.811 requirements, so it can act as the main source of time and frequency for the entire infrastructure.

Does Net.Time τ protect against spoofing and GPS loss?

Yes. The multi-band GNSS receiver increases resistance to interference and spoofing, and the rubidium oscillator provides holdover (time maintenance) after loss of the satellite signal – 100 ns for 10 hours.

Which time signals does Net.Time τ support?

PTP, NTP, SyncE, GNSS, ToD, n × 1PPS, IRIG-B, T1/E1, MHz – in any input/output combination, with translation between protocols.
